- In 2011, artist Hans-Peter Feldmann covered the walls of a gallery at the New York Guggenheim Museum with 100,000 one-dollar bills (Fig. P1.48). Approximately how much would it cost you to wallpaper your room in one-dollar bills, assuming the bills do not overlap? Consider the cost of the bills alone, not other supplies or labor costs. FIGURE P1.48For each of the following scenarios, refer to Figure 1.4 and Table 1.2 to determine which metric prefix on the meter is most appropriate for each of the following scenarios. (a) You want to tabulate the mean distance from the Sun for each planet in the solar system. (b) You want to compare the sizes of some common viruses to design a mechanical filter capable of blocking the pathogenic ones. (c) You want to list the diameters of all the elements on the periodic table. (d) You want to list the distances to all the stars that have now received any radio broadcasts sent from Earth 10 years ago. 1.2 Units and StandardsThe SI unit for temperature is
- 0²T მე2 ƏT B- Ət You know that T is temperature (K) and x is the x-coordinate, which is measured in meters. You also know that t is time (s) and the book uses à as the symbol for thermal conductivity, whose unit is W/m.K. What must be the units of Q and ß?Scientists are studying the temperature on a distant planet. They find that the surface temperature at one location is 25° Celsius. They also find that the temperature decreases by 3° Celsius for each kilometer you go up from the surface. Let T represent the temperature (in Celsius), and let H be the height above the surface (in kilometers). Write an equation relating T to H, and then graph your equation using the axes below. * T axis (y) goes up to 30 (counting by 5's) * H axis(x) goes up to 8 (counting by 1's) **Be sure to write out the points tooA physical chemist measures the temperature inside a vacuum chamber. Here is the result. T=-75.3 degrees celsius Convert to SI units. Round your answer to decimal place.
- A metal ball, which has a surface area of 175 cm2, is heated in a furnace to 678 oC. a)State the value of temperature in the correct SI units. State your answer as a whole number (and use this value as a whole number, if needed in subsequent calculations). b)State the area in correct SI units.
